SAGA to launch an Hadoop cluster as a normal batch job on Torque/PBS/SLURM clusters

Project description

# SAGA Hadoop

Last Updated: 10/01/2016

# Overview:

Use [SAGA](http://saga-project.github.io/saga-python/) to spawn an Hadoop Cluster within an HPC batch job.

Currently supported SAGA adaptors:

  • Fork
  • Torque

Requirements:

  • PBS/Torque cluster
  • Working directory should be on a shared filesystem

By default SAGA-Hadoop deploys an Hadoop 2.2.0 YARN cluster. The cluster can be customized by adjusting the templates for the Hadoop configuration files in core-site.xml, hdfs-site.xml, mapred-site.xml and yarn-site.xml in the hadoop2/bootstrap_hadoop2.py.

# Usage

Try to run a local Hadoop (e.g. for development and testing)

easy_install saga-hadoop saga-hadoop –resource fork://localhost

Try to run a Hadoop cluster inside a PBS/Torque job:

saga-hadoop –resource pbs+ssh://india.futuregrid.org –number_cores 8

Some Blog Posts about SAGA-Hadoop:

# Packages:

see hadoop1 for setting up a Hadoop 1.x.x cluster

see hadoop2 for setting up a Hadoop 2.7.x cluster

see spark for setting up a Spark 2.0.x cluster

see kafka for setting up a Kafka 0.10.x cluster

# Examples:

*Stampede:*

saga-hadoop –resource=slurm://localhost –queue=normal –walltime=239 –number_cores=256 –project=xxx

*Gordon:*

saga-hadoop –resource=pbs://localhost –walltime=59 –number_cores=16 –project=TG-CCR140028 –framework=spark

*Wrangler*

export JAVA_HOME=/usr/java/jdk1.8.0_45/ saga-hadoop –resource=slurm://localhost –queue=normal –walltime=59 –number_cores=24 –project=xxx
